Re: [flexcoders] Take two: dynamic asset creation
Dear Alex Harui, I think that will help! We just need to create a class with getInstance() method that returns the instance we need based on the parameter we passed to the constructor Say for example, BitmapFactory class that takes bitmapData as a parameter and returns a bitmapAsset using the given bitmapData when getInstance method is called myButton.icon = new BitmapFactory(myBitmapData); will get it right :) Regards, Arul - Original Message - From: Alex Harui To: flexcoders@yahoogroups.com Sent: Wednesday, October 24, 2007 1:27 AM Subject: RE: [flexcoders] Take two: dynamic asset creation That?s fine.

As an aside, the simplest solution is (I think) a very straightforward change to the Flex API. If the expected data fields were extended so that as well as 'icon' you passed in 'iconArguments' and those arguments, if present, were used as arguments to the asset constructor it would solve it all. And I don't think it would impact performance appreciably - the only difference is that internally Flex would call new SomeAssetClass(someArgs) instead of new SomeAssetClass(). The parameterisation of those constructors would open up so much more potential.

Subject: [flexcoders] Take two: dynamic asset creation
Here's an easier way to explain the problem I posted about earler.
If I create some BitmapAssets manually rathern than using embed:
var b1:BitmapAsset=new BitmapAsset(someBitmapData1);
var b2:BitmapAsset=new BitmapAsset(someBitmapData2);
var b3:BitmapAsset=new BitmapAsset(someBitmapData3);
How do I then pass them to something like a TileList, which expects an icon
property of type Class:
var rowData:Object={label:Some Label,icon:WhatGoesHere};
Where WhatGoesHere can't be BitmapAsset (that just produces an empty bitmap).
Nor can it be b1, because that's not of type Class.
The goal here is to achieve this without creating a new ItemRenderer.
Thanks in advance,
Ian
Re: [flexcoders] Take two: dynamic asset creation
Dear Ian,
Thanks for the links
Right now I'm stuck in the same place as Josh Tynjala . old school style
Function prototypes are not treated as Class. since flex components expect a
class it fails
But I'm going to dig further in the morning (now its 1 am in Singapore)

Thanks Arul,
The more I delve in to this and experiment with it the more I'm beginning
to think it's not possible.
Ben Stucki has an interesting post on a similar solution:
http://blog.benstucki.net/?p=42
But it relies on you needing to know exactly which component container the
resulting object is destined for, and that won't work in TileLists (because
ItemRenderers get reused).
Josh Tynjala has a slightly different solution:
http://www.zeuslabs.us/2007/09/28/actionscript-3-bitmap-image-classes-with-functions-and-loaders
But it hits the same issue that I did, which is that in AS3 Function!=Class
any more.
It feels like it _ought_ to be easy.
If it's really true that we can't use runtime-created assets with the Flex
framework without handrolling a load of different ItemRenderers or creating our
own subclasses of the Flex components, then that's very depressing and seems
ill-thought-out. :-(
Cheers,
Ian

And furthermore, what's the point of having that method? I would assume the
point of a util function would be to aggregate several common steps, but it
seems to me like they just changed name?
Array.indexOf() == ArrayUtil.getItemIndex() (functionality-wise)
So, what's the deal?

[flexcoders] Bug in Using the XMLListCollection class Example and the Fix
Any one tried this example?
Flex 2 Developer's
Guide Building User Interfaces forFlex Applications Using Data
Providers and Collections Using hierarchical data providers Using an
XML data provider
http://livedocs.macromedia.com/flex/2/docs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Partsfile=0513.html
"Using the XMLListCollection class" example has a
serious problem, when you delete an item in the List, if it is a leaf node in
the Tree it gets deleted too
This is happening because of cross references
that exist (we are directly adding the node toListwhich still
has references to myData, the tree dataProvider)
Solution to this problem is simple, we need to
make a copy to add to the list, then everything will be all right
we just need to change the doTreeSelect function
as follows
// Add the item selected in
the Tree to the List XMLList data provider. private function
doTreeSelect():void
{ if
(prodTree.selectedItem)
listDP.addItem(prodTree.selectedItem.copy());
}
I've attached thebug fixedMXML as
well

From Flex2_devguide.pf Notice that the built-in drag-and-drop functionality of the Tree control lets you move items.
